MASSACHUSETTS, ASSIGNOR OF ONE-HALF MODERMOTT, OF SAME PLACE.

SPECIFICATION To all whom, it may concern: l

Be it known that 1, JOHN M. GLEASON, a citizen of the United States,residing atLowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented certain new and useful Improvements inSewing- Machine Fans, of which the following is a specification.

My invention relates to a fan, supported upon the table of asewing-machine, or other light machine driven by foot-power, and adaptedto be operated by the motion of l the treadle of the machine. 1

In the accompanying drawings, Figure 1 is an oblique view of asewing-machine table with my invention attached. Fig. 2 is an enlargedelevation, showing the method of attaching the bell-crank lever and itssupport to the table, the fan-socket being in section; Fig. 3, anenlarged elevation of the lower bracket attached to the treadle. Fig. 4is a front elevation of parts shown in Fig. 8, representing the methodof attaching and adjusting the connecting-rod.

A'is the frame; B, the table; 0, the treadle, l rocking up on the shaftD, and connected at its rear end by the pitman to the wrist E on the lfly-wheel F, from which fly-wheel a sewingmachine (not shown) supportedon the table B is driven in the usual manner.

The above-named parts are of the usual construction and operation.

A bracket, G, has an open or forked end, 9 g, which receives the backedge of the table 13, and a set-screw, G, turning in the lower tine, g,of the fork, thrusts against the under side of the table and secures thebracket G to the table. To the rear end of the bracket G is pivoted at Ga bell-crank lever, H. The upper arm of the lever H is provided with ahollow or socket, H, in which the handle I of a palm-leaf or other fan,I, of similar shape, may be inserted. The handle I is retained in thesocket 11 by a set-screw, J, which turns in a threaded hole in the sideof said socket, and thrusts against said handle I. A bracket, K, similarto the bracket G, is forked at k k to take in the back edge of thetreadle.

under side of the treadle G, or directly against the treadle, and holdsthe bracket K in place. A connecting-rod, L, is pivoted at the lowerend, at L, to the outer end of the bracket K, and at the upper end, atL", to the outer end eration of the treadle in the usual manner to drivethe sewing-machine will give a reciproeating motion to the bellcranklever H and to the fan I,-and direct a current of air upon the operator,who sits at the front of the table.

The outer endof the lower bracket, K, is provided with an extension, Kin which are a number of holes, 0 0 0 into either of which of the lowerarm of the lever H; hence the opthe pivot may be inserted, according asthe height of the table above the treadle is greater or less, it beingintended that the handle I of the fan shall stand about perpendicularlywhen the fan is thrown back as far as possible.

ble by the holes 0 O 0 I can apply my fan to any of the sewing-machinesin commonuse. Each of the set-screws G J K should turn in a boss orthickened spot on the part which it enters, in order that such light aspossible.

Each pivot G L L consists of a nick-headed screw, which is smooth andcylindrical next its head and within the part which turns upon it, andis of reduced size near the point and threaded, as shown in Fig. 4, theshoulder Z, Fig. 4,'between the smooth part and the threaded part,preventing the pivot from entering far enough to bind the piece whichturns upon it.

The lower bracket, K, may have a recess at K to receive a rib or bead,G, such as is frequently cast around the edge of the treadle.

The fan above described operates only when the machine to which it isapplied is in morequire any great additional outlay of power to run it,requires no winding up or stopping, and is much cheaper than theclock-work fans sometimes used for a similar purpose. ,1

I claim as my invention- 1. The combination of the table and thetreadle, a bracket, means of securing the same to said table, abell-crank lever pivoted to the said bracket and adapted to receive theban means of the adjustment rendered possi- 0 parts may be as dle of afan, another bracket and means of seadjust-ably attaching saidconnecting-rod to 10 curing the same to said treadle, andaconnectsaidbracket, and means of attaching said ing-rod pivoted to said lever andto said last bracket to the treadle of a machine, as and for namedbracket, as and for the purpose spccithe purpose specified.
